Questions
What is the Adaptive Cards MCP server?
AI-powered Adaptive Card MCP server — 9 tools for generating, validating, optimizing cards for Teams, Outlook, Copilot, ChatGPT. npm: adaptive-cards-mcp
What tools does Adaptive Cards expose?
40 in total: 33 read-only, 7 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is Adaptive Cards safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does Adaptive Cards need?
It reads ANTHROPIC_API_KEY, AZURE_OPENAI_API_KEY, KEYWORDS, MCP_API_KEY, MCP_AUTH_MODE, OPENAI_API_KEY and POSTHOG_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does Adaptive Cards run?
It speaks sse and stdio, so it runs as a local process your client starts. It is published on npm as adaptive-cards-ai-vscode at 1.0.0.
How current is this page?
The grade is for one exact copy of the source (6c16e39493c3), read on 2026-10-08. The repository is watched and re-audited when it changes.
